there need not be a DHCPv6 server available at the ISP, rather ICMPv6 discover
messages will originate from this gateway and will be used for auto configuration. A
third option to specify the IP address and prefix length of a preferred DHCPv6
server is available as well.
Figure 24: IPv6 WAN Se tup page
Prefix Delegation: Select this option to request router advertisement prefix from any
available DHCPv6 servers available on the ISP, the obtained prefix is updated to the
advertised prefixes on the LAN side. This option can be selected only in Statesless
Address Auto Configuration mode of DHCPv6 Client.
When IPv6 is PPPoE type, the following PPPoE fields are enable d.
Username: Enter the username required to log in to the ISP.

3.2.8 Checking WAN Status
Setup > Internet Settings > WAN1 Status
The status and summary of configured settings for both WAN1, WAN2 and WAN3
are available on the WAN Status page. You can view the following key connection
status information for each WAN port:
Connection time: The connection uptime
Connection type: Dynamic IP or Static IP
Connection state: This is whether the WAN is connected or disconnected to
an ISP. The Link State is whether the physical WAN connection in place;
the Link State can be UP (i.e. cable inserted) while the WAN Connection
State is down.
IP address / subnet mask: IP Address assigned
Gateway IP address : WAN Gateway Address

The WAN status page allows you to Enable or Disable static WAN links. For WAN
settings that are dynamically received from the ISP, you can Renew or Release the
link parameters if required.

3.3 Bandwidth Controls
Advanced > Advanced Network > Traffic Management > Bandwidth Profiles
Bandwidth profiles allow you to regulate the traffic flow from the LAN to WAN 1 or
WAN 2. This is useful to ensure that low priority LAN users (like guests or HTTP
service) do not monopolize th
e available WAN’s bandwidth for cost
-savings or
bandwidth-priority-allocation purposes.
Bandwidth profiles configuration consists of enabling the bandwidth control feature
from the GUI and adding a profile which defines the control parameters. The profile
can then be associated with a traffic selector, so that bandwidth profile can be applied
to the traffic matching the selectors. Selectors are elements like IP addresses or
services that would trigger the configured bandwidth regulation.
Figure 26: List of Configure d Bandwidth Profile s
To create a new bandwidth profile, click Add in the List of Bandwidth Profiles. The
following configuration parameters are used to define a bandwidth profile:
Profile Name: This identifier is used to associate the configured profile to the
traffic selector
You can choose to limit the bandwidth either using priority or rate.
If using priority “Low”, “High”, and “Medium” can be selected.
If there
is a low priority profile associated with traffic selector A and a high
priority profile associated with traffic selector B, then the WAN
bandwidth allocation preference will be to traffic selector B packets .

For finer control, the Rate profile type can be used. With this option the
minimum and maximum bandwidth allowed by this profile can be limited.
Choose the WAN interface that the profile should be associated with .
Figure 27: Bandwidth Profile Configuratio n page
Advanced > Advanced Network > Traffic Management > Traffic Selectors
Once a profile has been created it can then be associated with a traffic flow from the
LAN to WAN. To create a traffic selector, click Add on the Traffic Selectors page.
Traffic selector configuration binds a bandwidth profile to a type or source of LAN
traffic with the following settings:
Available profiles: Assign one of the defined bandwidth profiles
Service: You can have the selected bandwidth regulation apply to a specific
service (i.e. FTP) from the LAN. If you do not see a service that you want, you
can configure a custom service through the
Advanced > Firewall Settings >
Custom Services
page. To have the profile apply to all services, selec t ANY.
Traffic Selector Match Type: this defines the parameter to filter against when
applying the bandwidth profile. A specific machine on the LAN can be
identified via IP address or MAC address, or the profile can apply to a LAN
port or VLAN group. As well a wireless network can be selected by its BSSID
for bandwidth shaping.
